In some European countries there is a common belief that calcium preparations have beneficial effect in curing allergic reactions of any origin. However there is no evidence-based data to justify this procedure. Now Hungarian doctor Dr. Hunor Novák – who is rather actively promoting evidence based medicine in wide range of media – launched an petition on his Facebook page against using calcium for these conditions. Many well known doctors and researchers joined so there is a good chance that this old will disappear soon in Hungary.
